Paraterminal gyrus

Paraterminal Gyrus is a small part of the brain located in the medial surface of the cerebral hemisphere, adjacent to the lamina terminalis. It is also known as the subcallosal area or the subcallosal gyrus.

Anatomy

The paraterminal gyrus is a narrow lamina on the medial surface of the hemisphere in front of the lamina terminalis. It is part of the limbic system, which is involved in emotion processing, learning, and memory. The paraterminal gyrus is located below the rostrum of the corpus callosum, and it is continuous with the orbital gyri at the base of the brain.

Function

The paraterminal gyrus is involved in several important brain functions. It is part of the limbic system, which is responsible for emotion, learning, memory, and behavior. The paraterminal gyrus is also involved in the regulation of the autonomic nervous system, which controls involuntary body functions such as heart rate and digestion.

Clinical significance

Abnormalities in the paraterminal gyrus have been associated with several neurological and psychiatric disorders. For example, changes in the size and shape of the paraterminal gyrus have been observed in patients with schizophrenia and bipolar disorder. In addition, damage to the paraterminal gyrus can result in cognitive and emotional deficits.
